Abstract

The purpose of the present invention is to prevent a grenade from rolling and being removed from an object when the grenade is thrown. A second safety pin (131), a second safety pin connecting hole (112), a second hanging ring (122), and a spring (123) are applied to an existing grenade in the present invention. Therefore, the present invention prevents a safety handle (121) from being removed from a fuse (110) when the grenade is thrown, and the safety handle (120) is fixed while being open.

Description

Grenade brake and its throwing method {Brake of Hand Grenade}

The present invention relates to grenades, and more particularly, to grenades to explode when a safe distance from the throwing area is secured.

Grenade is a weapon thrown by the throwing arm's arm force, which is a close combat weapon that ensures the safety of the thrower and has a narrow kill radius considering the flight time to the target. Therefore, the grenade effect can be maximized by the throwing ability. However, if there are structural restrictions, the result will be different. The spherical grenades currently in operation are fundamentally rolled inertia and structurally when throwing into the target, which causes them to deviate. If a grenade, the most effective and intimidating weapon used by an individual in close combat, can be accurately thrown at the target and overpower the target, the grenade can be a simple, solid precision strike weapon thrown by a person.

Currently, grenades are made lightly around an egg-shaped (Mills Bomb) and made into a spherical shape so that they can fly safely in the target direction over the existing grenade throwing distance and to minimize the number of debris from conventional splinters. The throwing distance and the effect were increased by adjusting the shape to the proper size, but when it falls to the target area accurately, it keeps rolling and deviating from the target due to the inertia force and the terrain condition. When throwing uphill to the high ground, the player rolls back from the target area, dealing no damage to the enemy and causing damage to allies or reducing its effectiveness. However, if the grenade thrown farther than the target rolls into the camp by using the reverse, the survivability of the throwing water is relatively low. Also, spherical grenades can be kicked easily when dropped into the base, making them easier to handle in grenades.

When defending, you throw down, limiting the grenade to roll off the slope and miss the target, causing damage to the enemy beyond the expected target.

The present invention aims to complement the fundamental structural problems of grenades so that they can be accurately thrown at the target.

It uses the features of Potato Masher-type grenades used by the German army to solve the problem of the current spherical grenades. The Potato Mixer is a grenades that are more familiar with bat grenades. The grenades have a handle on the grenades with bat-like handles.

Potato grenade-type grenades have many limitations, but the bat, which is the handle of the grenades, has a bat that falls on the target and acts as a brake that prevents the grenades from rolling. .

Therefore, in order to achieve the effect of hitting a target and throwing a grenade at the time of throwing the grenade, the structure of the existing spherical grenade grenade is removed, and the safety handle is removed when the grenade is removed and the grenade is thrown.

In order to increase the accuracy of grenades, it was designed to take advantage of the potato mixture type without changing the structure of the grenades. The role of the safety handle was to simply act as a brake when thrown from simply assisting the ball in the fuse.

Therefore, the safety handle of the grenade is not selectively removed from the fuse, and the safety pin and the safety ring are removed and thrown, and the safety handle is opened while the ball strikes the primer to operate the fuse while the safety handle is thrown in the open state. This allows the grenade to be thrown away while at the same time preventing the safety knob from acting as a brake and rolling off the target, thus improving the hit rate.

In order to prevent deviation from the target, which is the biggest disadvantage of spherical grenades currently in operation, it is necessary to ensure that the grenades reach the target accurately and burst simultaneously. To reach the target and explode at the same time, a highly skilled pitcher must boldly throw and take into account the delay and distance of the fuse. So current grenades, unlike ordinary bombs, have many limitations in hitting the target. Therefore, it was decided to prove the validity of the grenade of the present invention through the experiment whether the brake can act in the state that is not removed. The spherical grenades of the present invention and the grenades of the present invention were produced in-house and subjected to a throwing experiment. In the experiment, the slope and the flat land were selected and the spherical grenade and the grenade of the present invention were thrown under the same conditions. Since the terrain of the Korean Peninsula is composed of various operational areas such as mountainous terrain, wild land, and urban areas with high inclination, the terrain where the grenades are used for comparison can be compared for objective experiments. In this case, the throwing test of the spherical grenade and the grenade of the present invention was conducted.

division Spherical grenade Grenade of the present invention 10 to 15 ° 307/350 (87%) 15/350 (4%) 30 to 35 ° 337/350 times (96%) 35/350 (10%)

Table 1 shows the result of throwing the spherical grenades and the grenades of the present invention 350 times into the grassy terrain by dividing the slope into two (10-15 ° and 30-35 °). When spherical grenades were thrown 350 at 10-15 ° slopes, 307 (87%) were found to continue to roll off the target area and continue to roll on flat slopes. When thrown, only 15 (4%) left the target area. In addition, it was found that spherical grenades were thrown 350 times in a 30 to 35 ° terrain with a high inclination, and 337 (96%) missed the target and could not see the effects of grenades. %) Is out of goal. It was found that the rate of rolling was high according to the inclination, but the brake of the safety handle prevented the grenade from rolling and stopped the grenade. However, in terrains with more than 60 ° of inclination, most grenades rolled out showed limited brake role at high slopes.

division Spherical grenade Grenade of the present invention Average maximum at least Average maximum at least 25m 4.85 7.13 3.63 2.45 3.15 1.52 35m 9.23 10.37 7.40 5.64 6.20 3.51

Table 2 shows the results of how the rolled grenade leaves the target area by inertia without stopping it. The flat terrain was carried out in a general troop camp of Masato soil to obtain data under the same conditions of the experiment. The spherical grenades thrown from the plain and the grenades of the present invention rolled and separated the target distance 25m and 35m respectively and throwed 350 times. At 25m, the average grenade escape distance was 4.85m, at least 3.63m and at most 7.13m, and the grenade of the present invention had an average of 2.45m and a minimum of 1.52m to 3.15m. At 35m, the average grenade escape distance was 9.23m, at least 7.40m to 10.37m, and the grenade of the present invention was 7.64m at least 5.23m and at most 8.20m. Therefore, in the experiment confirming the accuracy of the thrown grenades, the grenades of the present invention having a grenade braking device than the spherical grenades in operation have a high accuracy.

Like the existing grenade, the grenade of the present invention has the first safety pin 130 is inserted into the first safety pin coupling hole 111 and passes through the first locking ring 121. Fuse 110 is coupled to the body 101, and throwing the first safety pin 130 from the grenade and throwing the safety handle open while the ball in the body 101 explodes after a few seconds hit the primer.

The safety handle of the existing grenade has a shape as shown in FIG. 5 so that the safety handle can be easily removed from the fuse. The U-shaped locking ring 123 allows the safety handle to be immediately removed from the fuse at the same time as the safety handle is opened.

The existing U-shaped locking ring 123 is replaced with a circular locking ring like the second locking ring 122 of FIG. 4 so that the safety handle 120 is not removed from the fuse 110 when the safety handle 120 is opened. .

As shown in FIG. 3, the second safety pin coupling hole 112 is formed on the side surface of the fuse of the existing grenade to insert the second safety pin 131 or the clamp 132 to secure the safety handle 120. . In the case of the second safety pin 131 can be removed, but in the case of the fastener 132 it is impossible to remove.

As shown in FIG. 6, the spring 124 is positioned between the fuse 110 and the safety handle 120, and the spring 124 may be fixed by the second safety pin 131 or the fastener 132 as shown in FIG. 7. As the spring 124, a coil spring, a leaf spring, or the like can be used.

Through the second safety pin 131, as shown in Figure 8 can be selected to remove or remove the safety handle 120. When using the clamp 132, it is not possible to remove the safety handle (120).

Check the target area to choose whether to remove or remove the safety grip 120 when throwing grenades. When the safety handle is not removed, only the first safety pin 130 of the first safety pin 130 and the second safety pin 131 is removed, and the grenade is thrown to throw the spring 124 as shown in FIG. ). At this time, the second safety pin 131 prevents the spring 124 and the safety handle 120 from being removed from the fuse 110. In the case of removing the safety handle, the safety handle 120 is removed from the fuse 110 when the first safety pin 130 and the second safety pin 131 are removed and thrown. In this way, it can be rolled after throwing like a conventional grenade.
